我按照官方教程http://struts.apache.org/getting-started/how-to-create-a-struts2-web-application.html进行了操作。但是当我运行webapp时总是抛出异常。我尝试了很多次，但我真的不知道如何重新开始它。
这是例外

好的，我知道原因。因为Struts现在不支持jdk9。你可以看到我创建的问题。 https://issues.apache.org/jira/projects/WW/issues/WW-4869?filter=allopenissues

删除路径前的jar:和file:\
D:\.m2\repository...
